Alghero's weather is typical of the Mediterranean region; hot summers with some scorchers in July and August and some rain in November and December. In general however, the city is quite dry.

As a rule of thumb,  unless you just happen to be unlucky, long days of sunshine are the norm, from the beginning of May until the end of September. That said, it is not at all unusual for the good weather to stretch for a month (or two at the end) either side of that period. For example, in the latter half of November last year, apart from the odd day, temperatures were still around 24 - 25C (mid 70s). In the heat of the summer there is the occasional, violent and spectacular thunderstorm, but these are short-lived.

Sardinia has more sunny days than anywhere else in Italy, averaging over 300 days per year.

The weather is usually good right through from May to the end of October. Winter is mild, although the region does experience some Mistral winds which usually last for about 3 days at a time.

Despite the advent of low-cost airlines, which have icreased access to and the popularity of Sardinia, the island does not cater for year round tourism. Whilst in Alghero, the season runs from May - October, almost everywhere else, it runs from June - September. In some resorts, most notably Porto Cervo, on the Costa Smeralda, everything is closed outside July - August. 

Potential visitors should realise that trains, buses and ferries often do not run outside High Season or run to very restricted timetables. The majority of hotels, agriturismo, B&B's and restaurants on the island are closed.  To avoid disappointment and significant wasted expenditure, It is very important  to ensure that transfers, and accomodation are available and confirmed prior to flights being booked. 

Provided that you have taken note of the advice above, the month of January is particularly interesting, owing to the "Secche di Gennaio." The Dry of January.  This phenomenon occurs every year, usually in the middle of the month, when there is no rain, the weather is fine and dry and temperatures reach and even exceed 20C.

The city celebrates a variety of religious festivals throughout the year and may be something to consider when planning your trip.  

New Year is celebrated with great enthusiasm, with a grand firework display over the harbour.

One of the best festivals of summer, "FerraGosto" takes place on 15th August and has a grand display of fireworks. Immediately after, the town celebrates outdoors eating fried fish. It is a great time to mingle with tourists and locals alike.

Later in the year, in November is the Festival di Santa Cecilia, a religious and music festival. April sees a truly cultural event representing its Catalan roots for the region, with the Ritta della Settimana Santa, or holy week. This is followed by more Easter celebrations that originated from the time when it was under Spain's ruling.

Summer is definitely the tourist season. The warm weather promotes a hot nightlife where pubcrawling the waterfront bars and enjoying live music or just sitting in the piazzas to relax after a day in the sun, are the favorite pastimes. But, December should not be ruled out, the ancient city sees a lot of charming decorations for the Christmas season making it a fine place for midwinter's jaunt.
